We’ve conducted the following analysis for each attribute
- defined descriptive statistics
- histogram
- scatterplot of data by hospital
- scatterplot of data by state
- map data
In addition, we’ve run a correlation analysis and then a linear regression model for all correlations greater than |0.5|
